Prosecutors allege Kinsella disposed a memory card from a cellphone possibly used to record the March 21, 2013, incident.

In one video from another cellphone posted to YouTube, one officer is seen pulling Octavius Johnson to the ground by the neck near 33rd and Seward streets. Then, a swarm of other officers chase one of Johnson's brothers into a home.

Officers had initially been sent to the area to investigate a parking complaint.

Soon after the YouTube video went viral, Omaha Police Chief Todd Schmaderer launched an investigation into allegations that police used excessive force. As a result, four officers – including a commanding officer – were relieved of duty. Other officers were reassigned.

Testimony revealed Kinsella did not find any video of the incident on the cellphone he recovered, but he still removed its memory card and threw it out a window.

Kinsella faces up to one year in prison and a $1,000 fine for each count.
